FIELD

The present invention relates to a method and a device for transmittingelectric power and signals between a stationary wall and a leafpivotally mounted on the wall, wherein the electric signal isgalvanically isolated, and is in particular inductively transmitted.

BACKGROUND

Such a method and such a device have previously been described in DE 3915 812 A1. DE 39, 15 812 A1 describes concentrically disposed coils or acylindrically formed capacitor for power transmission. A signaltransmission may likewise occur by means of the coils or the capacitoror via radio.

The disadvantage here is that during the transmission of signals bymeans of this same assembly, which is also used for the powertransmission, a mutual influence on the transmission cannot be excluded.An optimized power transmission also regularly requires a differentdesign adaptation of the coils and the capacitor as an optimized signaltransmission so that the use of this very same assembly of transmitterscan only ever be a less than optimal compromise.

If the signal is transmitted via radio, the device for powertransmission may in principle indeed be optimally designed for thispurpose. Radio transmission is, however, frequently susceptible toexternal interference and can be influenced with appropriate means byway of external transmitters, which is particularly disadvantageous withregard to security-related signals.

SUMMARY

An aspect of the present invention is to provide an improved method andan improved device for transmitting electric power and signals between astationary wall and a leaf pivotably mounted on the wall.

In an embodiment, the present invention provides a method fortransmitting electric power and signals between a wall and a leafpivotally mounted on the wall which includes transmitting the electricpower so as to be galvanically isolated, and transmitting the signalsoptically or optoelectronically. The present invention also provides adevice for transmitting electric power and signals between a wall and aleaf pivotally mounted about a hinge axis on the wall which includes apower transmission apparatus configured to galvanically isolate atransmission of the electric power, and a signal transmission apparatusconfigured to transmit at least one of an optical signal and anoptoelectronic signal.

DETAILED DESCRIPTION

In the method according to the present invention, the signals aretransmitted optically or optoelectronically between the wall and theleaf. The optical or optoelectronic transmission allows for very highdata transfer rates so that the signal transmission may also be carriedout digitally with high resolution. In contrast to radio transmission,optical or optoelectronic transmissions may also easily be completelyoutwardly shielded so that they are immune to external interference ortampering. An optical or optoelectronic signal transmission is lastlycharacterized by a very low power requirement so that the electric powerto be provided specifically for signal transmission is comparativelylow.

In an embodiment of the method according to the present invention, theelectric power is transmitted from a primary to a secondary side, andthe signals are transmitted from the secondary to the primary side.

The signals may be those which transmit the power demand from theanticipated secondary side consumer to the primary side so as to createa control loop which provides that, apart from losses from galvanicallyisolated transmission, only that electric power is conducted which theconsumer needs. The function of the control loop may be purely analog,that is, the power demand may be transmitted dependent on the intensityof the optically or optoelectronically transmitted electromagneticradiation.

The signals can serve to transmit operational and/or signal statusesfrom secondary side sensors, detectors or detector groups, for example,to a primary side alarm system. If only such signals are transmittedfrom the secondary side to the primary side via the method according tothe present invention, only such power is, for example, kept by theprimary side as is sufficient to operate the sensors, detectors ordetector groups. No need for a control loop exists.

In an embodiment of the present invention, the primary side can, forexample, be the wall side, and the secondary side can, for example, bethe leaf side. Sufficient electric power through a power connection isusually available on the wall side via most existing power connections.Routinely present on the leaf side are sensors, detectors or detectorgroups, such as glass break sensors, closure sensors, etc., the signalsof which must be utilized by a stationary, i.e., wall side, alarmsystem.

In an embodiment of the method according to the present invention, adirect current voltage can, for example, be made available on theprimary side, which direct current voltage is then converted into analternating current voltage having a frequency, for example, of between10 and 300 kHz, to be used for the galvanically isolated inductivetransmission. This direct current voltage can be provided by a powersupply of an alarm system which is buffered by a battery or accumulator.Interruption-free execution of the method is thereby provided as long asthe alarm system can be operated. The direct current voltage can beconverted into alternating current voltage using, for example, a powerMOSFET switch, which can be power controlled, for example, by a pulsewidth or a pulse phase control.

In an embodiment of the present invention, the primary and secondarycoil assemblies can, for example, have an identical construction. Theirimpedance and their housing and core material are optimized for theoperating frequency and the maximum power to be transmitted.

The device according to the present invention for transmitting electricpower and signals between a stationary wall and a leaf mounted pivotallyabout a hinge axis on the wall comprises a power transmission apparatusfor galvanically isolated transmission of the electric power. An opticalor optoelectronic signal transmission apparatus is provided according tothe present invention.

The power transmission apparatus can, for example, comprise a primaryand a secondary coil arrangement.

The signal transmission apparatus can, for example, comprise a lightemitting diode (LED) and a photodiode or a phototransistor.

In order to effect a power transmission with minimal loss and a signaltransfer which is as reliable as possible, the coil assemblies and thesignal transmission apparatus are designed so that they each have acentral axis, and are arranged so that the central axes approximatelycoincide with the hinge axis. During a pivoting movement of the leafabout the hinge axis, the coil assembly and the components of the signaltransmission apparatus, for example, the light emitting diode and thephototransistor, merely rotate relative to one another, and otherwise donot shift their positions with respect to one another. The primary andsecondary coil assemblies can, for example, have an identicalconstruction. Their impedance and their housing and core material areoptimized for the operating frequency and the maximum power to betransmitted.

In an embodiment, the device according to the present inventioncomprises a first power transmission apparatus for providing need-basedelectric power for leaf side consumers. Examples of leaf side consumersinclude motorized locks, lighting, etc. These consumers should beprovided with the power required for their function by the powertransmission apparatus. The primary power with which the primary coilassembly is acted on is thus adjusted to the particular leaf side powerrequirements.

To accomplish this adjustment, this embodiment can, for example,comprise a first signal transmission apparatus to control the electricpower which is provided by the first power transmission apparatus forleaf side consumers. Via this first signal transmission apparatus, acontrol circuit is created which provides that, apart from losses in thepower transmission apparatus and in the operation of these providedelectronic circuits themselves, only so much power flows into theprimary side of the power transmission apparatus as will be delivered tothe leaf side consumer. The necessary control can, for example, bepurely analog, and can, for example, be effected via a pulse widthcontrol or via a pulse phase control.

This embodiment of the device according to the present invention alsocomprises a second power transmission apparatus for providing thenecessary power for the operation of sensors, detectors or detectorgroups. This second power transmission apparatus may likewise compriseprimary and secondary side coil assemblies, wherein the primary coilassembly is disposed in turn on the wall side, and the secondary coilassembly is disposed on the leaf side. As sensors, detectors anddetector groups routinely have substantially lower power requirementscompared with consumers such as motorized locks, lighting, etc., andthis power requirement is substantially constant, a control circuit forcontrolling the primary power by which the second power transmissionapparatus is acted upon may therefore be dispensed with. The primary andsecondary coil assemblies can, for example, have an identicalconstruction. Their impedance and their housing and core material areoptimized for the operating frequency and the maximum power to betransmitted.

This embodiment of the device according to the present invention alsocomprises a second signal transmission apparatus. This only serves,however, to transmit operational and/or signal statuses from thesecondary side sensors, detectors or detector groups to a primary side,i.e., wall side, alarm system.

The separation of the power transmission necessary for operation of thesensors, detectors or detector groups from the power transmission forthe further, leaf side consumers has the advantage, among others, thatinterferences possibly resulting from sudden power fluctuations may beavoided. A less powerful, but therefore, for example, more robust andlonger-lasting, accumulator or battery backed primary voltage source mayalso be provided on the primary, i.e., wall side, thereby increasing theoperational reliability achievable with the device according to thepresent invention.

To enable the leaf to be adjusted in relation to the wall, and inparticular to also enable the leaf to be adjusted perpendicular to aframe surrounding the belt opening to be closed by the leaf, forexample, for the purpose of adjusting the sealing pressure withoutrequiring any further work on the device according to the presentinvention, the power and signal transmission apparatuses, can, forexample, be arranged to be transversely movable to the hinge axis in afirst receiving member of the leaf and/or arranged to be transverselymovable to the hinge axis in a second receiving member of the wall. Atleast one of the power transmission apparatuses can, for example, bemounted in a bearing sleeve therefor.

The bearing sleeve can, for example, be positioned transversely to thehinge axis in the first or second receiving member to allow for aclearance.

To prevent or at least impede contamination in the area between thefirst and second bearing sleeves, one of the first or second bearingsleeves can, for example, feature an edge which protrudes over thesurface facing the other respective bearing sleeve in the direction ofthe hinge axis and which covers the other respective bearing sleevelaterally across a section of its length in the direction of the hingeaxis, for example, with a clearance. The clearance enables additional,lateral and/or relative displacements of the leaf and wall members withrespect to each other, whereby the adjustability of the leaf in relationto the wall is extended perpendicular to the hinge axis.

The present invention will now be further illustrated with reference todrawings in which an exemplary embodiment of a device according to thepresent invention is shown.

The device in FIG. 1, designated as a whole by reference numeral 100,comprises two wall members 1, 2, which can be attached apart from oneanother along the direction of a hinge axis S to a wall having a door orwindow opening (which is not represented in the drawings). The precedingor subsequent use of the term “wall” includes a frame or trim, which isusually provided in the area of a door or window opening on a wall.

The wall members 1, 2 comprise attachment members 3, 4. Each attachmentmember 3, 4 has a hole 5 for receiving a fastening screw 6, and a hole 7for passing through electrical and/or optical cables 8, which are merelyindicated in FIG. 1 and which establish the electric or opticalconnection from the power or signal transmitters to the associatedelectronic or optoelectronic circuits, as will be described in moredetail below.

The wall typically forms a primary side PS, from which electric power istransferred to the leaf, which is the secondary side SS.

Respective receiving members 9, 10 for receiving components from powerand signal transmission apparatuses 11, 12 are integrally formed on eachattachment member 3, 4.

The device 100 also comprises a leaf member 13, which is disposedbetween the two wall members 1, 2. The leaf member 13 likewise comprisesan attachment member 14 and a receiving member 15 integrally formed onthe attachment member 14. Provided on the attachment member 14 is a hole16 for a fastening screw 17, with which the leaf member 13 is mountableon a leaf (which is not represented in the drawings). The attachmentmember 14 also has holes 18 which serve in the conveyance of electricaland/or optical cables 19, which once again are represented onlyschematically in the drawing. These cables 19 serve to connect the powerand signal transmission apparatuses 11, 12 with leaf side electronic oroptoelectronic circuits.

The receiving member 15 also serves to receive leaf side components ofthe power and signal transmission apparatuses 11, 12. These leaf sidecomponents comprise two bearing sleeves 20, 21 which are spaced apartfrom one another along the direction of the hinge axis S and are mountedmovably with respect to each other in this direction. A spindle drive 22is used for shifting and fixing in a desired position. The spindle drive22 comprises an adjusting spindle 23 which comprises a face gear 24 inthe center. This face gear 24 is used for the selective attachment of aturning tool (which is not represented in the drawings), or for theengagement of a rotary actuator apparatus (which is also not representedin the drawings). The adjusting spindle 23 also has two threadedportions 25, 26, which comprise outer threads oriented in oppositedirections. The threaded portions 25, 26 engage with complementaryinternal threads 27, 28 of the bearing sleeves 20, 21. The bearingsleeves 20, 21 can thus be shifted in the direction of the hinge axis byrotary action of the spindle drive 22 so as to be adjusted between amounting position, in which the bearing sleeves 20, 21 have a minimaldistance from one another, and an operating position, in which thebearing sleeves 20, 21 almost touch the bearing sleeves 29, 30 in thereceiving members 9, 10 of the wall members 1, 2.

The construction and mode of operation of the power and signaltransmission apparatuses 11, 12 will now be explained with reference toFIGS. 2 and 3, in which the signal transmission apparatus 12 in thelower portion of FIG. 1 may be recognized.

In addition to the bearing sleeve 21, which is slidably mounted in thereceiving member 15 of the leaf member 13 by the actuating spindle 23,the power and signal transmission apparatus 12 comprises the bearingsleeve 29, which is disposed in the receiving member 10. Thefunctionally corresponding bearing sleeve 30 is also disposed in thereceiving member 9 of the upper wall member 1. Displaceability of thebearing sleeves 29, 30 in the direction of the hinge axis S is notprovided. The upper bearing sleeve 30 comprises a radially projectingclamping apparatus 31, so as not to automatically fall out after apossible removal of the leaf portion 13.

A primary coil assembly, 32, 33 is inserted into the bearing sleeve 29,30, respectively. Each primary coil assembly 32, 33 comprises a coilhousing 34, 35 made of a soft magnetic, particularly ferritic material.The coil housings 34, 35 have a central core 36, 37, around which thecoil windings 38, 39 are led. A central hole 40 is provided in each core36, 37. The central hole 40 is used for receiving a phototransistor 41,42, respectively, which is part of the secondary member of anoptoelectronic signal transmission apparatus 43, 44, respectively.

A secondary coil assembly, 45, 46 is disposed in the bearing sleeve 20,21, respectively. The secondary coil assembly 45, 46 comprises in eachcase a coil housing 47, 48 having a core 49, 50 around which thesecondary coil winding 51, 52 is wound.

The coil housing 47, 48 has in turn a central bore 53, extending throughthe respective core 49, 50. The central bore 53 serves to accommodate ineach case a light emitting diode (LED) 54, 55, which need notnecessarily operate within the visible light range, but which isadjusted to the respective phototransistor 41, 42 with regard to thewavelength of the emitted electromagnetic radiation (visible orinvisible light).

The light emitting diodes 54, 55 belong to the respective primary partsof the signal transmission apparatus 43, 44.

To improve the optical coupling of the light emitting diodes 54, 55 tothe respective phototransistor 41, 42, optical fibers 56, 57 areprovided which are inserted from the mutually facing sides of the coilhousing into the central holes 40, 53, and are flush with the mutuallyfacing sides of the coil housing.

As can be seen in FIG. 3, the coil assemblies and the signaltransmission apparatuses are disposed symmetrically with respect to acentral axis A. In the assembled state, this axis A coincides with thehinge axis S.

As can be seen in FIG. 1, the device according to the present inventionhas two of the assemblies B represented in FIG. 3, each comprising oneapparatus for power transmission and one for signal transmission,whereby the two assemblies B are disposed opposite one another.

One of the assemblies B is part of an apparatus for providing on-demandelectric power for leaf side consumers. For the sake of description, itwill be assumed that this is the lower assembly B in FIG. 1. The primarycoil assembly 32 and the phototransistor 42 are then connected to aprimary power electronics system PLE, and the secondary coil assembly 45and the light emitting diode 54 are connected to a secondary powerelectronics system SLE. The primary coil assembly 32 and the secondarycoil assembly 45 are part of a first power transmission apparatus 96,and the primary coil assembly 33 and the secondary coil assembly 46 arepart of a second power transmission apparatus 97. The basic structure ofthe primary and secondary electronics systems and their modes ofoperation are explained in more detail with reference to FIG. 4.

The primary power electronics system PLE comprises a processor 58, whichvia an input 59 is powered with a 12V or 24V direct current voltage thatcan be provided by the power supply of an alarm system.

The processor 58 also has an input 60, via which the voltage output by aswitching regulator 61, which is supplied by the same voltage source,can be detected.

The processor 58 comprises an output 62 via which the processor 58 isconnected to a driver 63 of a MOSFET power stage 64.

On the input side, the MOSFET power stage 64 is connected to the outputof the switching regulator 61. The primary coil 32 is connected to theoutput of the MOSFET power stage 64.

The switching regulator 61 has a control input 65 via which the voltagethat is output by the switching regulator 61 can be altered. The controlinput 65 is connected to the phototransistor 42.

The secondary power electronics system SLE comprises a rectifier 66, towhose input the secondary coil assembly 45 is connected. A leaf sideconsumer 69 is connected to the output 67 of the rectifier 66, with asurge protector 68 connected in between.

The secondary power electronics system SLE also includes an apparatus 70for setpoint/actual value voltage comparison, which compares the voltageat the output 67 of the rectifier 66 (actual value) with a predeterminedreference value (12V or 24V). The apparatus 70 comprises a signal output71, to which the LED 54 is connected. The apparatus 70 generates avoltage signal at the signal output 71, which is applied analog to theLED 54 and determines the intensity of the emitted electromagneticradiation, and is dependent on the setpoint/actual value difference. Thesignal is detected by the phototransistor 42, and a signal-dependentvoltage value is transmitted to the control input 65 of the switchingregulator 61.

A control circuit is created by means of the primary and the secondarypower electronics systems PLE, SLE which provies that (apart from lossesin the primary and secondary electronics as well as through thegalvanically isolated transmission from the primary coil assembly 32 tothe secondary coil assembly 35) only so much power of the primary coilassembly 32 is supplied from the MOSFET power stage 64 as will bedelivered to the consumer 69.

The upper assembly B disposed in the device 100, which comprises thecorresponding primary coil assembly 33 and the secondary coil assembly46 as well as the phototransistor 41 and the LED 55, is part of a devicefor transmitting signals supplied by leaf side sensors, detectors ordetector groups of an alarm system. A primary signal electronics systemPSE and a secondary signal electronics system SSE are provided for thispurpose.

The primary signal electronics system PSE comprises a processor 72,which has a supply voltage input 73 for applying a 12V or 24V supplyvoltage. The supply voltage is provided by an external power supply orby the alarm system.

The processor 72 further comprises a terminal 74 to which the detectorgroup outputs of an alarm system are connected. The processor 72converts the signals received from the detector device outputs intoserial data, and encrypts them in order to effectively preventunauthorized capture of these signals during the subsequent galvanicallyisolated transmission from the primary coil assembly 33 to the secondarycoil assembly 46.

The processor 72 has an output 75 via which it is connected to a driver76 of a MOSFET power stage 77. The frequency-modulated converted serialdata are supplied to the MOSFET power stage 77 via the output 75 and thedriver 76.

An internal power supply 78 is also attached to the MOSFET power stage77. The MOSFET power stage 77 is connected to the primary coilassembly33 on the output side. During operation, the primary coilassembly 33 is therefore acted on by an alternating current voltage,which is frequency-modulated according to the signals obtained from theoutputs of alarm system detector groups.

The processor 72 further comprises inputs for voltage/current controlwhich are connected to the terminals of an activated resistor 79 in thepower supply line. The inputs are designated by reference numeral 80. Asignal input 81 is lastly provided on the processor 72, to which thephototransistor 41 is attached.

The secondary signal electronics system SSE also has a processor 82,which comprises a signal input 83 to which the secondary coil assembly46 is connected. The processor 82 detects the signals transmitted fromthe primary coil assembly 33 to the secondary coil assembly 46 via thesignal input 83 via a corresponding signal demodulation of the voltageproduced in the secondary coil assembly 46, which is likewisefrequency-modulated voltage.

In order to operate leaf side sensors, detectors or detector groups ofan alarm system, the secondary coil assembly 46 is attached to arectifier 84. For this purpose, the rectifier 84 comprises an output 85which is connected via a MOSFET 86 to a distributor 87 for acting on thesensors, detectors or detector groups with the supply voltage.

The distributor 87 has an output 88 which is connected to an input 89 ofthe processor 82, via which the processor 82 detects the sensors,detectors or detector groups via the supply voltage provided by thedistributor 87.

Depending on the detected supply voltage, the processor 82 controls anoutput 90, which is attached to the gate of the MOSFET 86.

The rectifier 84 has a further output 91. The output 91 is attached to apower supply 93 for external detectors via a further MOSFET 92. TheMOSFET 92 is in turn controlled by the processor 82 via an output 94which is connected to the gate.

The processor 82 lastly includes a signal output 95 by which signalsrecognized by the sensors, detectors or detector groups are supplied ina suitably modulated state to the LED 55. The correspondingly modulatedsignals are received by the phototransistor 41 and made available viathe terminal 74 to the processor 72 of the primary signal electronicssystem PSE, which suitably demodulates the signals and makes themavailable to the alarm system via the terminal 74.

FIG. 6 schematically shows a detailed diagram of a further developmentof the exemplary embodiment according to the present invention. In thisfurther development, bearing sleeve 30 is positioned in receiving member9 of wall member 1 with a radial clearance Rx. Bearing sleeve 21 islikewise positioned in receiving member 10 with a radial clearance Fx.

Bearing sleeve 30 comprises a radial edge 98 on its surface facingbearing sleeve 21 which laterally covers bearing sleeve 21 externallyacross a section of its length in the direction of hinge axis S, againwith a radial clearance Bx.

FIG. 6 only shows the upper assembly, which comprises a powertransmission apparatus, as well as a signal transmission apparatus. Itshould be understood that the corresponding lower assembly in FIG. 1 isalso able to be constructed in a similar fashion.

Due to radial clearances Fx and Rx between the bearing sleeves 21, 30and receiving members and also the radial clearance Bx between theradial edge 98 and the bearing sleeve 30 covered by the radial edge 98,the components with a clearance therebetween can be displaced, inrelation to each other, perpendicular to the hinge axis S. Amanipulation of the device according to the present invention is notrequired to displace the leaf 13 in relation to the wall 1,2 andperpendicular to the hinge axis S for the purposes of adjustment. It isunderstood that the scope for adjustment is determined by the size ofthe elected clearance.

Although unexpected, it became apparent that the potential lateralmisalignment of the axes does not influence the coupling quality of theprimary and secondary coils, nor that of the light emitting diodes andphototransistors of the signal transmission apparatuses, in a way thatreduces transmission quality.

The present invention is not limited to embodiments described herein;reference should be had to the appended claims.
